Even as the IPL spot-fixing probe expands into money laundering, tax evasion and hawala charges, Mumbai Police have made no headway in recovering the most crucial piece of evidence - the money paid to the Rajisthan Royals' trio of S. Sreesanth, Ajit Chandila and Ankeet Chavan.

It seems there's more than just spot-fixing plaguing the IPL. Details indicate that Sreesanth and his mysterious women may have had a huge role to play not just in the spot-fixing scandal but even beyond.

According to our sources, Mumbai Police have found at least a dozen profiles of models and aspiring actors from Sreesanth's laptop. The police is also investigating CCTV footage from the five star hotel where Sreesanth stayed.

The sources said at least a dozen women have been spotted with Sreesanth in the footage. It is believed that Sreesanth was screening the women for his brother's upcoming movie. But it's not yet clear whether these women had a role in the infamous spot-fixing scandal or were they only being auditioned for a Malayali movie.

Even as new revelations continue to rock the IPL, reports are coming in that the Enforcement Directorate and the Income Tax department will soon join the investigation.

Along with money laundering, the ED may also investigate alleged 'hawala' transactions during the exchange of money in the spot fixing scam.

The ED, which maintains a dossier on suspected hawala dealers, has already started scanning operations of hawala operators in big cities like Delhi, Mumbai, Bangalore, among others.

Spot-fixing does not only contravene forex laws but could also result in money laundering and tax evasion, the ED official said.

Initial probe inputs in the IPL spot-fixing case point to the possible use of illegal channels of money routing (hawala) to make payments and for pushing illegal cash between bookies and cricketers.

Meanwhile, Delhi Police have urged spectators and the general public to lodge complaints against S. Sreesanth, Ajit Chandila and Ankeet Chavan.

So far, Delhi Police have received two such complaints by spectators for the matches played in Mohali and Mumbai. The police wants to make the complainants witnesses in the case.

Earlier in the day, a Lucknow resident filed a PIL in the Supreme Court seeking a Special Investigation Team (SIT) probe into the spot-fixing and other alleged irregularities in IPL. The petitioner also sought a stay on the remaining four matches, including the final match of IPL-6, till the probe is completed.

Rajasthan Royals, on the other hand, lodged a complaint with Delhi Police against its three players -- Chandila, Sreesanth and Ankit Chavan -- accusing them of cheating and other charges.

Two fans, who watched the Rajasthan Royals matches in Chandhigarh and Mumbai, also approached police with complaints of cheating while voice samples police of Chandila and bookies Manan and Jiju Janardhan, a close friend of Sreesanth, were taken at the CFSL located in outer Delhi's Rohini.

BCCI's anti-corruption unit chief Ravi Sawani, who has been asked to head the probe in spot-fixing by the cricketing body, held a meeting with Delhi Police Commissioner Neeraj Kumar and other top officials and offered all help.

Police sources said Ranji player Babu Rao Yadav, who was in Railways team, was picked up for questioning from Delhi earlier in the day. "He is being questioned. It was he who allegedly arranged a meeting with Chandila and bookie Sunil Bhatia, who are already arrested.

"Yadav figured in the tapped conversations. He will be arrested if we find he is involved in it," a senior police official said.

Seventeen people -- three IPL players, two former players and 12 bookies-cum-fixers -- were arrested since last Thursday in connection with the case which rocked the cricketing world.
